Abstract

Trichoptera were collected in the Tasmanian WildernessWorld Heritage Area (WHA) between November 1998 and February 1999 using
automatic UV light traps, sweep nets and aquatic hand-picking. The surveys targeted the four species listed on the Tasmanian Threatened
Species Protection Act 1995 which had been recorded from the WHA: Taskiria mccubbini, Taskiropsyche lacustris (both endangered),
Orphninotrichia maculata (rare) and Oxyethira mienica (rare). In total 88 species were identified, approximately half of the 174 species
now known from Tasmania. Taskiria mccubbini and Taskiropsyche lacustris were recorded for the fi rst time since they were first collected
from the original Lake Pedder in 1965. Orphninotrichia maculatawas recorded from a new location. Diplectrona Iyella (rare) was recorded
from two widely separated sites and is a new threatened species record for the WHA. One species ofEcnomidae was newly recorded from
Tasmania.
